If you want an alternative form of written communication your dyslexia won't effect try learning braille... I'm sure you can find a keyboard in it and the appropriate resources are available. Its alot of work but if you want to write it may be the best way to get there short of waiting for passable text to speech software. That is getting closer every day though.
To expect your version of English just because of a comparatively minor disability is silly. I can barely read most of your posts. Any book you wrote as you type now would be unintelligible. The same as if I didn't edit anything. Do check out the less floppy font though. If that works for you then run with it.
